2500D not working with 7D

[clives]

Anyone else have problems using a 2500D flash on their 7D??

 

Purchased 7D in August..taken 9,600 images since. GREAT camera.

Great images. I am a happy guy.

 

However, it came with a 2500D flash and I've not used the flash

much. It did not seem to be working properly (erratic) so my dealer

gave me a new one a few weeks back. Seemed okay at first, but again,

I only used it once or twice.

 

Yesterday, I got it out and took a lot of pictures to test it. It

simply does not work properly. With exactly the same setup and

settings, the images are overexposed and underexposed..all over the

map. (If they were all one way or the other, I could take corrective

action ... but the exposures are all over the place.) Batteries are

fresh. I am NOT using D lenses, but the flash should still work with

Maxxum lenses. Had flash set on TTL and camera is defaulted to pre-

TTL. I've tried all combinations (even without D lenses) including

ADI settings. Nothing works including the recommended settings.

 

I am taking it back to my dealer and going to ask for a discount on

a 3600HS(D) or a 5600HS(D). (KM pulled out of Canada so getting

service is going to be tricky. My dealer is real good tho.)

 

Anyone else have these problems?

 

Thanks,

Which firmware version does the camera have?

1.10u

I took three consecutive images in my messy office. Ready light On for all exposures. All at about 2m from camera. P mode. About 50mm focal length. Here is the URL...(will try to hot link this)

Considering that you had the same problem with two different flashes, the problem may also be the camera.

Thanks for your interest. Apparently there is a history of some firmware/chip fault. I've a letter into KM international and to the Canadian KM agent. What is strange. I don't do much flash work, but took about 80 flash pictures at a social event last month (100-mm, f2.8 lens) with the second flash and they were all (90 percent) pretty good. Now the results are erratic. The camera in all other respects works flawlessly and I've taken 9,600 images in 14 weeks.

I am told by the KM service agent in Canada that the 7D and flash have to be returned for an adjustment of some sort--presumably a "firmware" upgrade. Most unfortunate and I will not do this until early 2006.

 

If anyone else has relevant information, please feel free to post.

 

Thanks. Clive
